The operation of the conventional example will be described below. (1) In Conventional Example 1, the microcomputer 17
Processes an input signal from the operation unit 16 and displays the contents input by the key on the LCD 18 which is a display unit. Further, the microcomputer 17 has a test switch 20.
Is keyed in as a test, and when the test mode is entered, the transmission code signal output from the transmission circuit unit 19 is sent to the LCD 18
To display. Also, if the air conditioner is not operating normally by this operation, display the transmission code on the remote controller to determine whether there is an abnormality inside the remote controller or if there is a problem after it is output. Separately, determine the abnormal part. (2) In Conventional Example 2, when the power of the air conditioner is turned on and the power of the remote controller is turned on, the flow of FIG. 10 starts. As shown in FIG. 10, in the state 22a, when the signal of the circuit state of the sensor circuit is received from the air conditioner, the state shifts to the state 22b, and in the state 22b, the contents are displayed in characters or figures on the LCD 18 of the remote controller. To display. In the state 22a, loop back is continued until a signal is received. By doing this, when there is an input signal from the air conditioner, the content is displayed on the LCD.
This display content makes it easy to understand the operating state of the air conditioner. (3) In Conventional Example 3, as shown in FIG. 11, after the check mode is started, the falling edge of the detection signal is detected in the state 23a, and when the falling edge is detected, the process proceeds to 23b. Invert the LCD output,
Loop back to state 23a. If the falling edge of the signal cannot be detected in the state 23a, loop back is performed until it is detected in the state 23a. By doing so, it is possible to confirm that signals are being transmitted and received. (4) In Conventional Example 4, power supply to the remote controller is normally performed by a transmission line in the market, but by using the power supply device 24, it is not necessary to connect an air conditioner or the like to the remote controller. When the remote controller is set to the shipping inspection mode by using the inspection jig 26, the operation key unit 27 and the display LCD unit 28 can be checked. When the operation key unit 27 is operated in this mode, the signal output from the operation key 27 is processed by the microcomputer 25, and a display command is output from the microcomputer 25 to the LCD 28. At this time, the operation key 27, the microcomputer 25, and the L
If the CD 28 is normal, the corresponding preset LCD is turned on. However, if there is an abnormality, the corresponding LCD does not light up, so that the display system can be checked in advance before shipping to the market. (5) In Conventional Example 5, the remote controller 29
The address display operating means 30 outputs the address display request signal to the air conditioner 32 via the signal transmitting means 31. When the receiving means 33 of the air conditioner 32 receives the output signal in response to the output signal, the address display recognizing means 34 recognizes that the address display request for itself has been output from the controller. Further, the air conditioner 32, which has recognized the address display request, displays its own address on the address display means 36 according to the address set value of its own address setting means 35. As described above, in the conventional example 5, the remote controller outputs the address display request, so that the address set value state of the air conditioner can be confirmed.

[0004]

(1) In the conventional example 1, the transmission circuit section 19 outputs a signal corresponding to the operation key output from the microcomputer 7 by operating the key operation section 16, and outputs the signal. LCD18 the transmission code
It is designed to be displayed on the LCD, and at this time, the LCD
The transmission code that is assumed to be output by the transmission circuit unit 19 is only displayed on 18, and the signal actually output by the transmission circuit unit 19 is not taken in. Therefore, there is a problem that the remote controller alone cannot confirm whether or not the transmission circuit unit 19 is actually outputting the transmission code. A test switch 20 is provided to define the start and end of the test mode.
This not only increases the number of switches, but also causes an erroneous operation by the end user, which may cause an erroneous diagnosis. Further, the conventional example 1 is limited to the wireless remote controller, and there is a problem that the reception capability of the wireless remote controller cannot be confirmed. (2) The second conventional example relates to a remote controller that displays a signal indicating the circuit state of the air conditioner, and this remote controller cannot perform its own self-diagnosis. If the circuit status is not displayed on the LCD of the remote controller, is the signal sent from the air conditioner, or is the signal sent, but it is not displayed on the LCD due to a failure of the remote controller. There is a problem that it cannot be determined. (3) In Conventional Example 3, since the display device is turned on / off in synchronization with the fall of the detection signal, when the communication is performed at high speed, the display change state of lighting / turning off the display device is severe. However, there is a problem that it cannot be detected by human eyes. (4) In Conventional Example 4, since the dedicated jig 26 for shifting the state of the remote controller to the inspection mode is indispensable, a trouble occurs in the market, and it is presumed that the cause of this trouble is the remote controller. If you do not have a dedicated jig, you can not process quickly. In addition, at this time, since it is necessary to remove the main body case in order to enter the inspection mode, there is a problem in that it takes time to perform a troublesome removal work process. (5) The conventional example 5 relates to a remote controller for confirming the setting state of the address of the air conditioner. In the conventional example 5, it is necessary to use another controller for the information display means, which is self-contained. There is a problem that the self-diagnosis cannot be performed in.

As described above, when an abnormality occurs in the remote controller of the conventional air conditioner that is connected to the indoor unit of the air conditioner and the outdoor unit by a transmission line and controls the operating state of the air conditioner. , It is difficult to determine which part of the remote controller, indoor unit, and outdoor unit is abnormal, and in order to handle the trouble with the prospective service of replacing the remote controller for the time being,
Troublesome removal work, increased processing time,
There was a problem that the cause of the trouble was erroneous and that the display change state of the display was so severe that it could not be detected by human eyes.

The present invention has been made in order to solve the above-mentioned problems, and accurately diagnoses a trouble point by self-diagnosis of only a remote controller, displays the result of the diagnosis in an easy-to-see manner, and obscures the troublesome service. The purpose of the present invention is to obtain a remote controller for an air conditioner that is easy to use and has high reliability, because it eliminates the need for replacement work and replacement time and enables the cause of trouble to be processed quickly and accurately.

EXAMPLES Example 1. The first embodiment of the present invention will be described in detail below with reference to FIGS. FIG. 1 is a configuration diagram of a remote controller that is connected to an indoor unit of an air conditioner and each unit controller (not shown) of an outdoor unit in a first embodiment by a transmission line and controls an operating state of an air conditioner. The remote controller 1 is an application microcomputer 2 that is a monitoring control unit that controls the operation of each device described later in the remote controller while monitoring the transmission signal from the remote controller 1 and the reception signal from the air conditioner. And a communication system microcomputer 3 which is a communication process for performing a communication process of a transmission signal from the remote controller 1 and a reception signal from the air conditioner,
A transmission / reception driver 4 which is connected to the air conditioner via an external transmission line and is a transmission / reception circuit unit for transmitting and receiving a signal between the air conditioner and the remote controller 1, and an external transmission line 5 connecting the air conditioner and the remote controller. , An indicator 6 for displaying the operating state of the air conditioner or the remote controller 1, an operation key unit 7 for the user to operate the operating state of the air conditioner with the remote controller 1, and an air from the remote controller 1. Various switch units 8 for defining the address setting value of the harmony machine, an application transmission line 9 newly provided for monitoring the transmission / transmission state between the transmission / reception driver and the communication microcomputer by the application microcomputer, and reception And a transmission line 10 provided for monitoring the transmission state.

Next, the transmission check flow of FIG. 2 will be described. First, when the operation key 7 is operated in the state 11a, the application microcomputer 2 outputs a signal corresponding to the operation of the operation key 7 to the communication microcomputer 3 in the next state 11b. Recognizes and remembers that it has transmitted the signal (11b). Next, state 11
In c, if the communication microcomputer 3 is normal,
In other words, in the case of Yes in 11c, the transmission data output from the application microcomputer 2 is recognized by the application microcomputer 2 via the transmission line 9, and the state proceeds to the state 11e. However, if the communication microcomputer 3 is abnormal (that is, No in 11c,
Case), it is not recognized, and in that case, the process proceeds to the state 11d. In the state 11d, the application microcomputer 2 obviously determines that the communication system microcomputer portion 3 has a defect, and causes the display unit 6 to display that fact. In the state 11e, the application microcomputer 2 recognizes that the transmission data is transferred from the communication microcomputer 3 to the transmission / reception driver 4, and proceeds to the next state 11f. Next state 11
If the transmission / reception driver 4 is normal in f (Yes), the data output from this transmission / reception driver returns to the transmission / reception driver again by self-back and is output to the transmission path inside the remote controller 1, It is transmitted to the application microcomputer 2. However, when the transmission / reception driver 4 is defective (No in 11f), no signal is transmitted from the transmission line 10 to the application microcomputer 2. Therefore, state 11f
In case of No, the display 6 indicates that the transmission / reception driver 4 is defective (state 11g). Also, state 11f
In the case of Yes (when a signal is detected), there is no problem in the series of operations in the transmission process, and accordingly, the fact is displayed on the display 6 (state 11h).

It is possible to obtain an economical and easy-to-use air conditioner remote controller with reduced potential service.

FIG. 4 is a display flow chart when a transmission signal is detected on the transmission line 9 and a reception signal is detected on the transmission line 10. In Conventional Example 3, the display is turned ON / O every time the falling edge of the signal is detected in synchronization with the detection waveform signal of FIG.
Although the FF is switched, in the present invention, the means described below is used so that a person can surely recognize the transmission and reception. That is, when the microcomputer 2 starts the control operation in the check mode by operating the operation key 7 described above, first, the count number N is set to 0 (13a).
Next, when the microcomputer 2 detects the falling waveform of the transmission or reception signal (13b), the current count number N is confirmed (13c). Next, the count number N is 0
In the case of, the timer is started (13d). At the next 13e, if the falling detection count number N does not reach the constant value i while the time of the started timer has passed the constant time (in the case of No at 13e), the next 1
Go to 3f, add 1 to the count number N at 13f,
Proceed to the next 13g.

At the next 13g, if the time of the timer started after detecting the falling edge for the first time has not passed a certain time, the process loops back to 13b. That is, set on the timer-until the fixed time has passed, 13b, 13e, 1
Repeat 3f, 13g loop. When the falling detection count number N is a constant value i (Yes in 13e) by this repetition, the count N is reset, the timer is initialized (13i), and the content of the detected signal is displayed on the display unit 6. It is displayed for a fixed time (13j), and after the lapse of a fixed time, the display is turned off (13k), and then looped back to 13b. In addition, the above 13b, 13e, 13f, 13g
While the loop is repeating, when the timer is set-the fixed time has passed (Yes in 13g), the process proceeds to 13h, the count N is reset, and the timer is initialized (13
h), loop back to 13b. By the above means
Within a certain time preset within the timer (within a predetermined time)
In addition, only when a certain number of falling times are counted,
Since the detection signal is displayed for a certain period of time, a malfunction signal due to noise can be prevented and an accurate detection signal can be easily perceived by a person, making the air conditioner easy to use and highly reliable. You can get the remote controller.

Next, the input / display operation of the operation key section 7 and the display section 6 will be described with reference to FIGS. When the operation key section 7 is pressed in the check mode (14
a), the application microcomputer 2 recognizing that the key has been pressed turns on the characters or the lamp 6d of the display 6 shown in FIG. 6 (14b). At this time, the application microcomputer 2 checks which key of the operation key unit 7 has been pressed (14c).

For example, when the key 7a of the operation key portion 7 is pressed, the character or the lamp 6a of the display 6 of FIG. 6 is turned on (14d). Similarly, when the key 7b is pressed, the character or the lamp 6b is turned on (14e), and when the key 7c is pressed, the character or the lamp 6c is turned on (14f). The operation / display system is diagnosed based on the above basic operation, that is, each operation key 7a to key 7c.
If 6d does not light up even though is input (pressed), it is determined that the operation key unit is defective, and 6a, 6b, and 6c even though 6d is lighted up.
If none of these lights up, it is determined that the display unit 6 is defective.

As described above, since the states of the operation keys and the display can be simply known in the market, which could only be done at the time of shipment, it is possible to detect connection failure or LCD failure due to high frequency use. The remote controller of the air conditioner can be obtained which is easy to use, has good usability, and is highly reliable.

FIG. 8 is a flow chart when the setting state of the switch 8 on the substrate of the controller body is monitored in the check mode. When the switch 8 is switched to the monitor mode (15a), the operating condition of the air conditioner set by the switch is simultaneously monitored (15b), and the condition is displayed on the display 6 (15c). This function saves the trouble of removing the main body case.
